MANGLE.

SPECIFICATION forming part of Letters Patent N o. 683,402, datedSeptember 24, 1901. Application iiled August 24,190@ Serial No. 27,92I.(No model.)

To all whom, t may concern:

Beit known that I, CHARLES R. HoYT, a citizen of the United States, anda resident of Arlington, county of Middlesex, State of Massachusetts,have invented certain new and useful Improvements in Mangles, of whichthe following is a specification.

The invention herein set forth relates to man gles, and is particularlyintended to overcome certain difficulties at present encountered in thisclass of machines.

I'Ieretofore it has been proposed to employ a concavo-convex heated bedin combination with a slatted or ventilated cylinder provided with ajacket of felt or similar material and a traveling apron adapted tocarry the piece to be ironed over the convex surface of the heated bed,from which point the piece is then carried between the jacketed cylinderand the concave surface of the bed, after which it may be delivered toanother similar bed and cylinder. While this construction is entirelypractical, it has been found that the action of the heated bed upon thefelt forming the covering of the cylinder results in drawing through tothe outer surface of the felt covering particles of iron rust, which areformed on the cylinder by reason of the fact that the jacket rarelybecomes thoroughly dried out. This makes it necessary to frequentlyrenew the coverings, besides leading to the frequent spotting orstaining of the goods with iron rust. This invention is intended tocompletely overcome said difficulty, besides securing other practicaladvantages; and it consists, generally speaking, in the combination of aheated concave-convex bed, a heated cylinder coperating therewith, andan apron of felt or the like arranged to pass around both surfaces ofthe coneavo-convex bed andfover the surface of the heated cylinder. Thisand other features of my invention will be more particularly describedand pointed out in the following specication and will be clearly definedin the claims.

In the accompanying drawingIhave shown one of the forms of embodying theprinciples of my invention. v

The ligure shown is a vertical sectional view of such a machine, suchparts being shown as are necessary to a complete understanding of myinvention.

In any suitable form of framework is mounted a rotatable unjacketedcylinder a, constructed to retain steam under pressure, which may beadlnitted through a suitable steam pipe b. Beneath this cylinder ismounted a concavo-convex bed c, which is also supplied with steamthrough suitable apertures. In the frame there is also mounted a secondcylinder d, preferably steamheated. Beneath this cylinder d is a concavesteam-heated bed f. If, as in the present case, the apron c is notpassed between the cylinder d and the bed f, I provide said cylinder elwith a covering or jacket of felt, (indicated at d.) An endless apron offelt or the like is arranged to travel along the under or convex surfaceof the bed c, whence it passes back between the concave surface and theheated cylinder d and around said cylinder to the roll g, at which pointthe piece leaves the apron and passesbetween the jacketed roll d and itscoperating bed f. The rotation of the roll cl in the direction of thearrow serves to carry the piece being ironed between the roll d and thebedfin such a manner that the reverse face of the piece comes in contactwith the metal surface of the bed, so that both faces are given a finishon a metal surface. It will be understood that the goods are fed in atthe right-hand endof the machine upon the apron e at the point where itpasses over the roll h. -The apron itself may be provided with suitableguide, driving, and adjusting rolls. It-will be noticed that the sameface of the goods is kept in contact with both surfaces of the first bedc and that the reverse face is kept in contact with the surface of thebed f. Besides preventing the rotting out of the covering or jacket andthe spotting of the goods with iron-rust, this con'- struction andarrangement tends to give better results in the way of finish by reasonof the fact that the moisture is more rapidly eX- pelled from the apronunder the conditions to which it is subjected than it was from the feltcovering on the perforated roll.

It will be understood that considerable changes in form, construction,and arrange- IOO ment may; be vrmade without departingfrom theprinciples of my invention. Y Y

Without attempting to set forth the manifold changes in details ofconstruction that may be made in my invention, what I claim l. VIn amangle `the combination of a steamcylinder, a concavo-convex bed, meansfor heating the saine and an apron arranged to travel against the convexsurface of the bed and to pass thence between the bed and the cylinderand around the cylinder whereby the piece to be ironed may be carried bythe apron in contact with both faces of the bed while the moisture isbeing simultaneously expelled from the apron by contact with the heatedsurface of the cylinder substantially as described.

2. In a mangle the combination of the unjacketed cylinder, theconcave-convex bed, means for heating said cylinder and said bed, asecondary cylinder, a concave bed coperating therewith, and an apronarranged to travel over both surfaces of the Iirstvbed and around itscooperating cylinder and to deliver the piece being ironed to the secondcylinder and bed substantially as described.

3. In a mangle the combination of the ironing-bedadapted to lb e heatedand its coperating unjacked cylinder and means for heating saidcylinder, a roll g, a secondary cylinder provided with a felt jacket, aheated bed arranged beneath said secondary cylinder to cooperatetherewith, and an apron of felt arranged to pass between the firstcylinder and its coperating bed and around said cylinder and around theroll g substantially as described. In witness whereof I have hereuntoset my hand this 14th day of August, 1900.

CHARLES R. IIOYT. In presence of Gno. N. GODDARD, KATHARINE A. DUGAN.
